Cassandra is not working on server - ConnectException: 'Connection refused (Connection refused)'

I purchased a server(Singapore zone, 512 MB RAM) I tried to setup single node cluster in that server. I followed from this link when I checked $ sudo service Cassandra status It was showing

nodetool: Failed to connect to '127.0.0.1:7199' - ConnectException: 'Connection refused (Connection refused)'.

I tried to resolve using this stackoverflow link still it showing same error. Then I tried to setup it using tar file form this apache official when I checked with $ ./nodetool status Still I am getting same issue.

Note:- With local machine it is working fine.

I am unable to figure out why i am getting problem with server. I think "Nodes seem to freeze after some period of time" because I checked that after starting node it is killed. I tried to get some idea from this link

Review the system.log and debug.log.

I'm pretty sure that Cassandra node needs more than 512mb RAM to run.

Here, the recommendation is 4gb minimum:
